Cheese powder microbiological test: salmonella

Hi everyone,
I just have a question that there is a different meaning when Salmonella testing results are displayed in two following ways:
1/ 0 cfu/25 g
2/ 0 cfu/125 g
Hope to get thorough meaning of these.

Thank you very much!

It just shows that there is no presence of colony forming units (cfu) in your product, so no indication of salmonella.
